Pull Request Overview

This PR adds support for a callback method to control tab closing behavior in the Layout component. The callback allows consumers to implement custom logic that can prevent a tab from being closed by returning false.

• Added OnCloseTabItemAsync parameter to the Layout component that accepts a callback function
• Passed the new parameter through to the underlying Tab component which already supports this functionality
